Sad news for fans of MTV stuntfest Jackass: Daredevil driver Ryan Dunn, one of the many thrillseeking stars of the hit cable show, died early this morning after a gruesome car accident in his home state of Pennsylvania.
Jackass cohorts including Margera, Jason "Wee-Man" Acuña, and Steve-O have been expressing their shock and sadness at Dunn's death via Twitter throughout the day, including a touching tweet from Johnny Knoxville stating, "Today I lost my brother Ryan Dunn."
Margera is currently scheduled to make a special appearance at American Junkie in Scottsdale later this week to host the bar's Wednesday night party. According to American Junkie employees there's been no word as of this writing if Margera's appearance will be rescheduled or cancelled outright.
